函数可以访问两种不同作用域中的变量:全局(global)和局部(local)。Python有一种更科学的用于描述变量作用域的名称,即命名空间(namespace)。任何在函数中赋值的变量默认都是被分配到局部命名空间(local namespace)中的。局部命名空间是在函数被调用时创建的,函数参数会立即填入该命名空间。在函数执行完毕之后,局部命名...
在global scope 中,locals()和globals()返回global namespace的同一个字典。 dir([object]): Without arguments, return the list of names in the current local scope (similar tolocals().keys()). With an argument, attempt to return a list of valid attributes for that object. 不带参数时,返回当前...
Namespaces refer to sections(程序段) within which a particular name is unique and unrelated to the same name in other namespaces. 命名空间是一个程序段,在这个程序段内,每一个名称是唯一的,并且和其它命名空间中的命名空间无关. A namespace ia s a space that holds a bunch of names, and its a...

In Python, we can imagine a namespace as a mapping of every name we have defined to corresponding objects. It is used to store the values ofvariablesand other objects in the program, and to associate them with a specific name. This allows us to use the same name for different variables...
